"Infrastructure is an important support for economic and social development. We should coordinate development and security, optimize the layout, structure, function and development mode of infrastructure, build a modern infrastructure system, and lay a solid foundation for building a modern socialist country in an all-round way.". Why should we strengthen infrastructure construction at present? How to build a modern infrastructure system? Xinhua News Agency reporters interviewed industry experts and scholars for interpretation. Comprehensively strengthening infrastructure construction "is of great significance" Infrastructure construction is a basic, leading, strategic and leading industry of the national economy. The meeting pointed out: "comprehensively strengthening infrastructure construction is of great significance to ensure national security, unblock the domestic cycle, promote the domestic and international double cycle, expand domestic demand and promote high-quality development." Since the 18th CPC National Congress, China has made a number of world leading achievements in major scientific and technological facilities, water conservancy projects, transportation hubs, information infrastructure and national strategic reserves, and the overall level of infrastructure has been improved by leaps and bounds. But at the same time, compared with the needs of national development and security, China's infrastructure still does not meet the needs, and there are still many blocking points and difficulties in infrastructure construction. "It should be noted that there are still obvious shortcomings in the fields of rural revitalization, high-quality urban life and supporting industrial transformation and upgrading, especially in the functional layout, interconnection and comprehensive benefits related to infrastructure need to be further strengthened." Long Haibo, a researcher at the development research center of the State Council, said. Infrastructure is an important support for economic and social development. Compared with the traditional "railway public infrastructure" project, the comprehensive strengthening of infrastructure construction covers a wide range, and pays more attention to network-based, industrial upgrading, urban, agricultural and rural, national security and other infrastructure, which needs to be planned in advance and overall layout. It is noteworthy that in the outline of the 14th five year plan, "building a modern infrastructure system" is regarded as a part of the chapter "accelerating the development of a modern industrial system and consolidating and strengthening the foundation of the real economy". Long Haibo said that the meeting of the central financial and Economic Commission will comprehensively strengthen infrastructure construction as an important topic, and its importance is self-evident. "First, it is conducive to give better play to the 'multiplier effect' of infrastructure, continuously deepen the supply side structural reform, further expand domestic demand through infrastructure investment, and then drive the transformation and upgrading of manufacturing industry; second, it is conducive to better highlight the 'mainstay' role of infrastructure and continuously improve the toughness, stability and security of China's industrial chain supply chain; third, it is conducive to better reflect the 'public attribute' of infrastructure and continuously improve the competitiveness of manufacturing industry Meet the people's yearning for high-quality urban life and happy and beautiful countryside. " Build a modern infrastructure system and clarify the "construction blueprint" In view of the blocking points and difficulties existing in the current infrastructure construction, how to promote the construction of modern infrastructure system? "We should adhere to the people-centered development idea", "speed up the construction of new infrastructure and improve the level of traditional infrastructure", "we should be driven by multiple wheels and give full play to the various roles of the government and the market, the central and local governments, state-owned capital and social capital"... This meeting defined the "construction blueprint" for building a modern infrastructure system at present and in the future. "This is a strategic consideration based on the current and long-term, based on overall development and security. It is also a manifestation of the CPC Central Committee taking precautions in the face of the unprecedented changes in the world in a century and the superimposed impact of the epidemic in the century." Long Haibo believes that the central government has made it clear that continuously promoting work in many aspects and anchoring blocking points and short boards will further release the investment potential led by infrastructure construction and promote high-quality economic development. To improve the level of traditional infrastructure, we need to open up the "blood" and strengthen connectivity. The meeting pointed out that we should strengthen the construction of network infrastructure such as transportation, energy and water conservancy, focus on networking, network supplement and chain strengthening, and strive to improve network efficiency. It also puts forward clear requirements on accelerating the construction of the main framework of the national comprehensive three-dimensional transportation network, developing the distributed smart grid, and accelerating the construction of the main framework and main artery of the national water network. To accelerate the construction of new infrastructure, we need to implement accurate policies and optimize the structure. The meeting pointed out that it is necessary to strengthen the upgrading infrastructure construction of information, science and technology, logistics and other industries, lay out and build a new generation of supercomputing, cloud computing, artificial intelligence platform, broadband infrastructure network and other facilities, promote the layout construction of major science and technology infrastructure, strengthen the construction of comprehensive transportation hubs and collection and distribution systems, and lay out and build a number of regional airports, general airports and freight airports. Industry insiders pointed out that the wide range and large scale of infrastructure studied at this meeting is not only the need of current stable growth, but also the strategic layout that lays a good foundation for the country's medium and long-term development. The series of deployment will undoubtedly promote the advance implementation of the infrastructure planning of the 14th five year plan, drive the development of infrastructure construction and related industries in the near future, and bring development opportunities to relevant enterprises. Moderately advanced and scientifically planned "both economic accounts and comprehensive accounts" At present, investment in many fields has made efforts to ensure steady growth. Comprehensively strengthen infrastructure construction, how to ensure scientific and orderly, and avoid embarking on the extensive old road of "flood irrigation"? "We should be moderately ahead of schedule and lay out the infrastructure that is conducive to leading industrial development and safeguarding national security. At the same time, we should grasp the degree of ahead of schedule construction", "we should make scientific planning, implement the new development concept, base on the whole life cycle, coordinate the layout of all kinds of infrastructure, and realize interconnection, joint construction and sharing, coordination and linkage", "we should pay attention to benefits, calculate both economic accounts and comprehensive accounts, and improve the comprehensive benefits of infrastructure in the whole life cycle" ... meeting to make further deployment. Experts said that we should always take meeting the needs of the people as the starting point and foothold of infrastructure planning and construction, resolutely avoid face projects and image projects in the process of construction and development, and do not mistakenly equate infrastructure construction with boosting local GDP. "Solve the problems in progress through development, and strive to make the people fully enjoy the dividends of infrastructure development. The planning, design, construction and operation of infrastructure closely focus on the needs of the people and fully consider the demands of various groups." Long Haibo said. How to strengthen the support and guarantee of infrastructure construction? The meeting stressed that under the unified leadership of the Party Central Committee, we should establish a coordination mechanism for major infrastructure construction, coordinate the planning and construction of infrastructure in various fields and regions, and strengthen the guarantee of resource elements such as land, sea and energy. "To carry out infrastructure investment moderately ahead of schedule is to focus on the requirements of giving consideration to short-term stable growth and long-term structural adjustment." Liu Lifeng, a researcher at the Investment Research Institute of the Chinese Academy of macroeconomics, said that strengthening infrastructure construction should not only calculate the economic account, but also the comprehensive account, give full play to the leverage effect of funds, influence and drive the synchronous implementation of local government and social investment, and inject new vitality and impetus into economic growth.
